46PFL9706K, DLNA, 2 sound tracks: No Sound played

Hi all,

I'd like to stream my videos via DLNA from Windows Media Player to my 46PFL9706K TV. My videos are in MP4 format using h264 and AAC encodings. When playing videos with only one AAC sound track, everything is fine. But when I try to play a video file with two or more AAC sound tracks, I end up having no sound at all.

Windows Media Player itself or VLC both play the sound for the very same video file.

I create my videos using handbrake and I tried to reencode one video with xmedia-recode but it didn't help.

Have any of you experienced related issues? Are there some tipps you could give me? Because, frankly, I'm out of ideas here :-)

Hi Erik.

Welcome to the forums.

The reason why you don't get any sound when playing a file with 2 or more audio tracks is because the TV's only supports 1 audio track over DLNA.

Well, that's almost too easy then, of course. I thought I had read about other Philips TVs that only used the first of multiple audio streams, but still at least played the first one - while mine remains silent.
Is this a software issue to be addressed some time or will it stay this way?

Hi again Erik.

I will have a second look into this. Could you please share the media info of one of the files not playing with 2 audio tracks?

I copied a test file to a USB stick and connected that stick to the TV. First, the video wasn't displayed by the TV. I changed the file's extension from ".m4v" to ".mp4". After that, the video on the USB stick was listed. Still no sound however.

I have sent you a download link to the very same test video (still with .m4v extension however) in a PN.

Thank you very much for having a look into this.

Hi Erik.

Thank you so much.

Could you please confirm to me what DLNA media servers you have tried? and if the same as stated in first post, could you please try another server (example: twonky, tversity, ushare, mediatomb) and post the result back?

Hello Benedickte.

Thank you for your response.

Originally, I only tried the Windows 7 Home Premium built-in Windows Media Player to stream my media.
Following your post I have installed twonky and tversity (ushare and mediatomb don't seem to offer Windows binaries). Except for configuring the path to my test videos, I used the default settings of both programs respectively. The results were just like before: A video with one audio tracks would play fine, with two audio track file I sent to you, the TV remains silent.

Is there anything else I could try? I already thought of resetting my TV to factory defaults, but then refrained from it since I don't know if it would do anything good. I would rather rely on the specialists :-)

Thus, thank you very much for investigating!

Best Regards,

Erik

P.S.
As an additional test I tried to play the very same video offered by all three DLNA Servers installed (WMP, Twonky, Tversity) on my PS3. This works fine, audio is played here.
I also tried the video to play from another Windows 7 PC with WMP, still no luck regarding sound.

(i.e. there is no generation data given). I have never done a software upgrade on the TV and when I try now, it still says "No updates available". The TV's software version is the one the TV shipped a year ago.
